LUBRICATING DEVICE FOR JOURNAL-BOXES.

Specification of Letters Patent.

Patented. July 21, 1914 Application filed March 8, 1912. Serial No. 682,560.

To all whom it may concern: Be it known that I, J OHANN MARTIN Lass- MAN, a subject of the Emperor of Russia,

residing at 45 Greece street, Taganrog, in

., the Empire of Russia, have invented certain new and'useful Improvements in Lubricating Devices for J ournal-Boxes, of which the following is a specification.

The present invention relates to a special method of automatically supplying lubricant from below to axle ends and also to the construction of an axle box for this purpose,

and is characterized by the fact that the lubricant is supplied from below to the axle box by ineans of a piston pump arranged in-' side the box and operated by means of a crank which is arranged on the extremity of the axle end.

An axle box embodying the invention is illustrated by way of example in the accom panying drawing, inwhich:

Figure 1 is a longitudinal section of the box on the line AB in Fig. 2. Fig. 2 is a front elevation and section ontheline C-l inFig.l.-

The lubricating device consists of a box 9 with removable cover 10 provided with the parts of a pistonpump and with a lubricating' cup. The entire lubricating device isreadily removable for the purpose of examining and-cleaning the axle box. The lubricant box 9 arranged in the axle box with its partitions 10 and 11 and the openings 7 9 facilitates the separation of the oil from any admixturespresent. The lubricant is poured in through the front cover of the axle box until thelubricant box 9 is cov-.

'ered. The oil reaches the lower part of the lubricant box, runs down onto the bottom of the axle box 10, fills the space between the box 9 and the axle box, reaches the hole 9, and passes into the interior of the lubricant box from which it passes under the projection 11 from the cover of the lubricant box and over the partition 10 into the chamber 12 of the pump reservoir and gradually fills the entire box. On its way. the oil sepa rates from the admixtures of higher specific gravity and when it enters the pump cham-'' her it is already purified. The oil-required for lubricating is supplied from the chamber 12 by the pump during the running of the. train; this pump is driven by the rotating axle. With this object the pump piston 13 is mounted on a pm. 14 which 1s eccentric relatively to the axis of the axle. The movement of the piston causes the oil to pass through the ball valve 15 beneath the piston of the pump and thereupon in the downward movement of the piston oil is forced through the passage 16 and the ball valve 17 -into the cup 18 which is applied to the axle by the spring 19 so that the oil flows over the lower part of the axle end-and adheres to its surface, lubricates the bearing and flows back to the pump chamber along the path described becoming separated from water, metal, sand and the like on its way. The oil "supplied collects on the periphery of the axle and is thrown ofi in all directions by the rotary movement of the axle; A portion of the 011 passes beneath the part 20 and as it runs along the nose 21 it also lubricates the pin 14.- and the pump piston 13.

What I claim and desire to secure by Letters Patent ofthe United States is 1. In combination, an axle, an axle box, a lubricant receptacle contained in saidaxle box, a cover for said receptacle, a pump chamber in communication with said receptacle, means formed by said receptacle and said cover to prevent foreign matter from pfiissing with the lubricant into said pump c amber, a pump in said pump chamber and \ifneans to operate positively the said pump rom said axle to force the lubricant steadily from said receptacle onto said axle.

2. In combination, an axle, an axle box, a lubricant receptacle containedin said axle box and having an inlet for the lubricant, a cover. for said receptacle, a pump chamber in communication" with said receptacle,

means formed by said receptacle and said cover to prevent foreign admixtures from pas'singalong with the lubricant into said pump chamber, a pump in said pump chamber, a delivery funnel, means to hold said funnel in resilient contact with said axle,

and means to operate said pump positivelyw from said axle' to discharge the lubricant steadily from said receptacle through said funnel onto the axle.

3. In combinatiom-an axle, an axle box, a reservoir for containing lubricantlocatedin said axle, box, a cover for said reservoir formed w'ith a channel, a pump chamber-i communicating with said reservoir and with said channel at one end of the latter, a ball valve to interrupt the fiow of lubricant frgnjh said reservoir'mto said channel, a delivery funnel located at the. other end of said chair nel, a ball valve inthe' neck of said funnel,

a pump in said pump'chamber, and driving means connected with and eccentrically disposed relatively to said axleto operate said pump to force the lubricant from the reservoir past the first mentioned ball valve, along said channel, past the second. mentioned ball valve intosaidfunn'el'," thence onto the. axle.

4. In combination, an axle, an axlebo'x, a

' lubricant disposed f reservoir for contalnin 1n Sfild axle box, a rea 11y removable reservoir cover COIIIPIlSlDg a pump chamber and a lubricant delivery funnel both in communiranged in said pump charn cation with said,reserv0ir, the said pump chamber andthe neck of said being both formed as one iece, a pump arer and means to operate said pump positiv 1y from said axle to force the lubricant steal ilyfrom said reserv'oir through'said' funnel onto said axle.

In testimony whereof I afiixmy signature in-presence of two Witnesses.
